tracing/infrastructure: separate event tracer from event support
Add a new config option, CONFIG_EVENT_TRACING that gets selected when CONFIG_TRACING is selected and adds everything needed by the stuff in trace_export - basically all the event tracing support needed by e.g. bprint, minus the actual events, which are only included if CONFIG_EVENT_TRACER is selected. So CONFIG_EVENT_TRACER can be used to turn on or off the generated events (what I think of as the 'event tracer'), while CONFIG_EVENT_TRACING turns on or off the base event tracing support used by both the event tracer and the other things such as bprint that can't be configured out.
